TWINE AND METHOD OF MAKING SAME.

SIPECIFIGATION formingpart of Letters Patent No. 520,249, dated May 22,1894. Application filed September 14, 1889. Serial No. 23,915.($pecimens.)

To all whom it may concern:

Be it known that I, FARMER R001) WIL- LIAMS, of Beloit, in the county ofRock and State of Wisconsin, have invented certain Improvements in Twineand Methods of Making the Same, of which the following is aspecification. I

This invention is directed more particularly to the production of acheap, strong and pliable twine adapted for use in grain-bindingmachines.

The invention consists in the method of manufacturing twine by foldingor coiling a strip of paper and thereafter winding the same around acentral core of fibrous material, and, also in the improved twineresulting from such operation.

I am aware that a fiat paper strip has been wound spirally around afibrous core, and this I do not claim. When the paper is thus appliedthe strip is strained unequally and is frequently ruptured from theedges inward, the twine being weak and unreliable. By first folding orcoiling the paper into tubular or tape-like form, then winding it aroundthe core, I am enabled to utilize the'full tensile strength of both thepaper and the fiber, and to produce a twine which answers all practicalrequirements for the purpose named.

My core may consist of hemp, cotton, jute or other fibers of suitablestrength, laid loosely in the direction of the length of the twine, ortwisted, braided or otherwise united in any of the modes commonlypracticed in the manufacture of twine.

The paper may be of any stock and quality possessing the requisitestrength and pliability, and it may be twisted, folded or otherwiseformed into tubular shape. One or more of these tubes, either with orwithout being previously flattened or collapsed, is wound upon thecentral core in any manner which will secure close and permanent unionof the two.

In the accompanying drawings,-Figure 1 is a perspective View showing mycord in one of its forms and the method of producing the same. Fig. 2 isa cross section of the same. Fig. 8, shows the strip rolled into a tube,and Fig. 4, shows it folded down flat from both edges.

In Fig. 1 A represents the fibrous core of ordinary twine or cordcomposed of fibers twisted into strands which are in turn twistedtogether.

Bis the paper covering consisting of a paper strip coiled helically intoa tube, as at b, and then wound helically and tightly around the core A,so as to cover, conceal, and strengthen the same. There may be two ormore of these paper covering strands wound upon the core as indicated.

In Fig. 3 the paper strip is rolled edgewise into a tube; it may beapplied to the fibrous 'core in this condition.-

In Fig. 4 the edges of the strip are folded in upon each other andflattened down, and in this form the strip is wound upon the core. Thisfolded strip presenting several thicknesses is practically the same as aflattened tube and is a substantial equivalent of the coiled or foldedtubes of the preceding figures.

Having thus described my invention, what I claim is- 1. The method ofmanufacturing twine consisting in first folding or coiling a strip ofpaper on itself and thereafter Winding such coiled or folded strip upona core of fibrous material, whereby a pliable twine is produced in whichlongitudinal strains will be safely distributed throughout the paper.

2. The improved twine consisting of a fibrous core and a previouslycoiled or folded strand of paper wound thereon.

In testimony whereof I hereunto set my hand, this 12th day of September,1889, in the presence of two attesting witnesses.
